BUTCHER BLOCK SCRAPER AND CLEANER Henry E. Burgoon, Fremont, QhioApplication November 28, 1947, Serial No 788,478

2 Cl ims- 1 This invention appertains to novel and useful improvementsin devices for cleaning and scraping butcher blocks.

An object of this invention is to provide means for scraping the uppersurface of a butcher block, thereby cleaning the same.

Another object of this invention is to provide adjustable means adaptedto be gripped by the hand, whereby the eiiiective length of brushelements may be regulated.

Another purpose of this invention is to provide improved means forretaining brush elements in a device for scraping butcher blocks.

Another purpose of this invention is to provide extremely simple deviceof the character described which lends itself well to commercialmanufacture.

Ancillary objects and features of novelty will become apparent to thoseskilled in the art, in following the description of the preferred formof the invention, illustrated in the'accompanying drawings, wherein:

Figure l is a sectional view of the preferred form of the invention;

Figure 2 is a sectional view taken substantially on the line 2--2 ofFigure 1 and in the direction of the arrows;

Figure 3 is a bottom view of the device with the showing of the housingand the top retaining plate excluded therefrom;

Figure 4 is a detailed sectional view illustrating particularly themeans for clamping the brush elements in the device.

This invention has been conceived and developed for the purpose ofproviding a device for cleaning butcher blocks and also for scraping thesame. Heretofore, this operation was performed manually by use of wirebrushes, knives and other manually operative tools or instruments.

It is within the purview of the present invention to provide a poweractuated device which is readily manipulated and which may be adjustedfor various depths of cut to be taken, as dictated by the condition ofthe butcher block and the type of wood utilized therein.

A housing In is provided, preferably of circular configuration and has acollar 12 extending therefrom. An aperture (unnumbered) is pro- Y videdin the said collar for the purpose of receiving any suitable frictionsecuring means such as the set screw l4.

Received in the said collar 12 is a bearing l5, which is adjustablerelative to the longitudinal axis of the said collar l2 through themedium of the friction securing means M.

A suitable drive shaft l8 which may be a portion of a flexible shaftconstruction or the like, extends through the opening in the bearing 16and is spaced therefrom by means .of a sleeve 20. This sleeve 20 may bethreadedly received on. the said shaft 18 and is provided with a pair ofperipheral flanges 22 and 24 respectively. These flanges retain thebearing !6 in a desired position relative to the sleeve 20. Of course,the said flanges 22 and 24 respectively serve the purpose of thrustbearings, limiting the axial travel of the bearing 16.

Also provided in the said housing In is an improved means for retainingbrush elements 26. A plate 28 having a flange 3!! therearound isprovided on the shaft 18. A backing nut 32 may be supplied on the saidshaft I8 and serves the purpose of a thrust bearing for the said plate.28. A second plate 34 having a plurality of apertures 36 therein isfirmly seated against the lower portion of the said plate 28. Anothernut 38 may then be supplied on the said shaft !8 for the purpose ofmaintaining the plates 34 and 28 respectively in the proper juxtaposedposition.

Slots (unnumbered) are provided in the lower plate 34 and communicatewith the said apertures 36. A small shaft 49 is supplied in each of thesaid slot and has a plurality of brush elements 25 wrapped therearound.These brush elements may be of any suitable material such as springsteel, bronze Or the like.

By the aforementioned structure, it is readily apparent that the brushelements may be and are detachably received between the said plates atand 28 respectively and also, the effective length (that portion of theelements extending below the housing it), of the elements is adjusted bymanipulation of the said housing on the bearing 15.

To further assist in retaining the lower and upper plates 28 and 3:respectively in the locked or juxtaposed relative positions, a pluralityof screws, rivet or the like 44 may be supplied about the edge of thelower plate 34.

Of course, any suitable source of torque may be used in association withthe said shaft l8 such as an electric motor or the like. In assembly,the bearing is is disposed between the flanges 22 and 2A of said sleeve20. Any known expedient for placing these two elements in this relationis resorted to as having the hearing it split so that it may be insertedbetween the flanges. Then the screw I4 is passed through a hole in thecollar l2 so that it presses firmly against the bearing I6. The shaft I8is threaded in the bore of the sleeve 20 and the jamb nut 32 tightenedagainst the bottom flange 24 of the sleeve 20 so as to lock the sleeve,nut 32 and shaft [8 assembled.

After threading the brush elements 26 through the apertures 36 andarranging the plates 34 and 28 in nested relation, the lower end of theshaft I3 is passed through the central apertures in these plates and thenut 38 applied.

The device is now in readiness for operation to clean butcher blocks orany other surface adaptable to be cleaned by, an article of this nature.

Having described the invention What is claimed as new is:

1. A butcher block scraper comprising a housing having an open end and acover over the opposite end, said cover having an opening of smallerdiameter than said open end, a collar fixed to the cover and disposedaround said opening, a bearing disposed in said collar and means passedthrough an aperture in said collar retaining said bearing in said collarin selected axially 1 adjusted positions, a sleeve mounted in saidbearing for rotation and axial adjustment therewith, a shaft passedthrough and fixed to said sleeve, a first plate disposed in saidhousing, a

second plate superposed on said first plate and disposed in said housingand having a plurality of apertures, brush elements having their endspassed through said apertures, portions of the brush elementsintermediate their ends being clamped between said plates, and meansadjustably carried by said shaft and disposed above and below saidplates holding said plates together to retain said brush elementssubstantially immovable relative to said plates.

2. A butcher block scraper comprising a housing having an open end and acover over the .said recess being disposed in confronting relation Withsaid first plate and having a plurality of apertures opening in saidrecess and passed through said second plate, brush elements having theirends passed through said apertures, intermediate portions of saidelements being disposed in said recess and contacting both of saidplates,- means carried by said shaft holding said plates together toretain said brush elements substantially immovable relative to saidplates, 9. portion of said last mentioned means engaging said sleeve andlocking said shaft to said sleeve.
